An external indication of the existing diversity is the variety of names for the relevant institutions, sometimes differing even within a single country, such as: “fictive” dispossession of the grantor; non-possessory pledge; registered pledge; nantissement; warrant; hypothèque; “contractual privilege”; bill of sale; chattel mortgage; and trust.
Un claro reflejo de la diversidad existente es la multitud de denominaciones empleadas, incluso en el interior de un solo país, tales como: desposesión “ficticia”; prenda sin desplazamiento; prenda inscrita en un registro; nantissement (prenda de inmuebles); certificado de prenda; hypothèque; “privilegio contractual”; certificado de venta; chattel mortgage (hipoteca mobiliaria del common law); y trust (derecho real fiduciario, propio del common law).
